    RCA RTRU5540-D noise on right side of the panel

    Got a TV with strange problem.
    There is noise on the panel right side, sometimes blocky as in the picture, sometimes all over the place like lots of bad pixels. On a black image it's like night sky with stars.
    It feels to me like poor signal integrity.
    So far tried another T-Con and it was the same.
    Reseating connectors, applying heat, touching and flexing didn't reveal any clues.
    It seems like panel issue, but I'd like to hear other opinions especially if something similar was seen before.

      TCL 55S425 few horizontal lines, potential failure on both side of panel/buffer board
      by howardc64
      All left and right refers to looking from rear of TV (or looking from front with TV upside down)
      • TV came with vertical bars and no image. Found faulty TVS on left buffer board. Also replaced T-Con (may have damaged the original while hot air removing components, board has slight warp) and have full image but few horizontal lines on the screen. Some of the lines appears to be 2 pixel tall while others are 1 pixel tall.
      • Disconnecting left and right buffer board potentially reveals problems on both sides with different signals (unless this T-Con require jumper like Samsung FB_TRDY1&3) Fault

      LG 49UJ6500 LCD panel lighter band that goes away
      by howardc64
      49UJ6500 LCD panel has a lighter band on top when first powered on. Goes away (or gets much fainter) after TV on for a few min. After powered off for awhile and power back on, same band appears. If powered on immediately after powering off, no or much fainter band. Running the latest firmware.

      Disassembled the TV and lifted the LCD panel during testing. Band is on the LCD panel (can see the band on the panel as I lift it slightly) Backlight is perfectly even at the top edge. Double checked LCD panel alignment in the frame and is perfect but since band moved with the panel, its on...

      QN55Q60R Service Menu Panel Help
      by Storyteller12
      I had a the above tv qn55q60r that had a bad panel but everything else good. I had another panel here from un55nu6900 with bad leds and melted diffusers.

      I put the nu6900 panel in and powered it up and it does work but there are lines vertical lines.

      I was trying to change the panel type in the service menu but don’t see my exact panel. Anyway to fix this or someone have similar experience.

      the clear picture is the panel type from the service menus on the nu6900. The other 1 is the panel type that was set for the q60r with the bad panel....

      Panasonic 55DX600u second fault - panel brightness pulsing on right side
      by fixxy88
      After getting the backlights up and running a second fault has emerged on this TV. I was going accept defeat and move on but thought I'd have a quick look at it in case it was something simple. The right side of the display exhibits a panel brightness (not backlight brightness) pulse every 2-3 seconds in a stable timing.

      I poked about on the TCON test points and found one voltage that is fluctuating in the same pattern. VGH-ODD (Pin 47 of U10) is sitting at ~-6.5v then goes up to ~28v when the brightness pulses then goes back down to ~-6.5v again in a repeating pattern.

      43UM7100PLB, no picture but have half picture when i disconnect 1 side of panel
      by sigmeyer
      Like the title says , this is a very interesting problem , never experienced this before so i thought i'd share and maybe get some help on this. So the problem is as such: TV comes on , some gibberish flashes on screen and the screen remains black , the owner of tv said he heard sound. Now i checked some things cleaned all connections first of all so i dont run in a circle. Then i disconnected one of the cables for the panel , and viola, the left side of screen comes on, then i tried to switch it , with left side disconnected and right connected. Same problem persists. I checked some voltages...
